Washington and Tehran could return to compliance with an Obama-era nuclear deal within weeks, a senior Biden administration official said Thursday.
The official added that the final decision is in the hand of the Islamic Republic of Iran.
The senior State Department official, who talked to reporters on the condition of anonymity, said that the last three rounds have helped to "crystallize" what both nations need to do to return to mutual compliance.
Iranian government is facing severe financial difficulties and a local crisis since 2018 after the US former president Donald Trump withdrew from the deal and imposed new rounds of sanction on Tehran.
The two countries are currently negotiating to revive the deal.
"If Iran makes the political decision that it genuinely wants to return to the JCPOA as the JCPOA was negotiated, then it could be done relatively quickly and implementation could be relatively swift," the official said. "But we don't know if Iran has made that decision. We don't know if they've decided that they're prepared for a strict mutual return to compliance and whether they're prepared to do so now."
